BQ24259RGER Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the high-current paths is recommended. Keep the input and output capacitors close to the IC, and use a Kelvin connection for the sense resistors.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 1-2.2 μH). Consider the inductor's physical size, core material, and operating frequency.
  • The BQ24259RGER can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and prevent overheating.
  • Use the FB pin to set the output voltage. Connect a resistive divider from the output voltage to the FB pin, and calculate the resistor values using the datasheet's equations.
  • The EN pin is an active-high enable input. Connect it to a logic high (e.g., VCC) to enable the converter, and connect it to a logic low (e.g., GND) to disable it. Use a pull-down resistor to ensure the converter is disabled during power-up.
